CORN-HORSE.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed October 1, 1906. Serial No. 337,010.

To whom it may concern;

Be it known that l, EDWARD HENRY DEV- ILBIss, a citizen of the United States, residing at Westminster, in the county of Carroll and State of Maryland, have invented certain new and useful Improvements in Corn- Horses, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in devices or frames for forming shocks of corn; and it consists in the novel construction, combination, and arrangement of parts, hereinafter described and claimed.

The object of the invention is to provide a device of this character which is of simple, durable, and comparatively inexpensive con struction, which will be very effective for the purpose intended, and which may be readily removed from the shock after the latter is completed without disturbing the same.

Further objects and advantages of the invention, as well as the structural features by means of which they are attained, will be made clear by an examination of the follow ing specification, taken in connection with the accompanying drawings, in which Figure 1 is a perspective view of my improved corn-shock frame set up for use. Fig. 2 is a top plan. view of one end of the same, on an enlarged scale, showing the supportingarms in their closed position in full lines and in their open position in dotted lines. Fig. 3 is a side elevation of the parts shown in Fig. 2.

In the practice of my invention I employ a long bar or beam 1 of suitable width and thickness and provide adjacent to one of its ends two diverging supporting-legs 2, so that said beam may be supported upon the ground in an inclined position, as shown in Fig. 1. Upon the top of the main beam 1. adjacent to its elevated end'is secured, by screws or the like, a plate 3, upon. which are pivoted two supporting-arms 4. These arms have their inner ends pivoted upon screw studs or bolts 5, projecting upwardly from the plate 3 in transverse alinement, and they have pivoted to them by bolts or the like 6 the outer ends of curved links 7, the inner ends of which latter are similarly pivoted, as at 8, upon a plate or sliding head 9. The latter has detachably pivoted upon its top by a bolt or the like 10 the inner end of an operating-rod 11, arranged for sli ding movement in two guides 12, here shown in the form of staples arranged in longitudinal alinement upon the top of the elevated end of the main beam 1. The rod 11 has its outer end bent to form a hand-loop 13, and at an intermediate point it is bent upon itself, as shown at 14, to provide a notch or recess 15, adapted to engage a keeper 16, arranged upon the elevated end of the beam 1. This keeper 16 is in the form of a right-angularly bent plate, one end of which is secured by a screw or the like upon said beam 1, and the other of which is beveled and arranged to extend transversely of said beam and in longitudinal alinement with the guides 12.

Arranged upon the rod 11 is a coil-spring 17, which is confined between the innermost guide-staple 12 and a stop-collar 18, fixed upon said rod. The spring 17 serves to normally force the operating-rod 11 outwardly, so as to swing the supporting-armed in 1011- gitudinal alinement with each other or at right angles to the beam 1, in which position they are locked by the engagement of the notch or recess 15 in the rod 11 with the beveled end of the keeper 16, as shown in Fig. 1. The inward swinging movement of the arms 4 is limited by a stop 19 in the form of a stud projecting upwardly from the center of the attaching-plate 3, so as to be engaged by the inner edges of said arms as they-are swung inwardly into longitudinal alinement with the beam 1, as shown in full lines in Figs. 2, 3. The provision of the stop 19 prevents the centers of the pivots6 from passing the cen ters of the pivots 5 and thereby locking the arms in their closed position.

The construction, use, and advantages of the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that when the device is set up for use, as shown in Fig. 1, the corn is stacked upon both sides of the supporting-arms 4 and the adjacent portions of the beam and is then tied in the usual manner. To remove the frame or device from the shock, the handle 13 is grasped and the rod 11 elevated sufiiciently to disengage its notch '15 from the kee er-plate 16. The rod 11 may then be pus ied inwardly against the tension of the spring 17 so that the arms 14 will be swung inwardly owing to the connection of the links 7 with the plate or head 9 upon the inner end of said rod. As the rod 11 is thus moved in wardly the beam 1 is pulled longitudinally in the direction of its elevated end out of the shock. While the rod 11 may be pushed inwardly by hand this will not be necessary, since the longitudinal movement of the beam 1 as it is pulled out of the shock will cause the arms 4 to swing inwardly to their closed position, this movement of the arms being caused by the corn of the shock. As soon as the device is removed from the shock the spring 17 will move the rod 11 outwardly to swing the arms 4 at right angles to the beam 1, in which position they will be automatically locked when the notch 15 engages the keeper 16, the device being thus ready for making another shock.

Having thus described what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A corn-shock frame comprising a beam, legs for supporting the latter in an inclined my said invention,

position, an attaching-plate upon said beam, supportingarms pivoted at their inner ends in transverse alineme'nt upon said plate, a stud projecting from said attaching-plate to limit the inward swinging movement of said arms, guide-staples arranged uponsaid beam in longitudinal alinement, an operating-rod slidable in said guide-staples and bent to form a notch or recess, a keeper-plate upon said beam for engagement by said notch or recess, curved links having their ends pivotally connected to said rod and to said arms, a stop-collar upon said rod and a coil-spring upon said rod confined between said stopcollar and one of said guidestaples, substantially as shown and for the purpose set forth.

2. A corn-shock frame comprising a beam adapted to have one of its ends rest upon the ground and serve as a leg, diverging legs fixed upon said beam adjacent to its other end for supporting it in an inclined position, an attachingplate upon said beam, supporting- I arms pivoted at their inner ends in transverse alinement upon said plate, a pin proj j ecting from said plate adjacent to said arms and adapted to be engaged by the inner edges of said arms to limit their inward swinging movement, guide-staples arranged upon said beam in longitudinal alinement, an operating-rod slidable in said staples and bent intermediate its ends to form a notch or recess, and at its rear end to form a hand-loop, a keeper-plate secured upon said beam and having a laterally-projecting portion to enter the notch or recess in said rod, a plate secured upon the front end of said rod, longitudinally-curved links pivoted upon the lastmentioned plate and to said supportingarms, a collar fixed upon said rod, and a coilspring surrounding said rod and confined between said collar and one of said guide-staples, substantially as shown and for the purposes set forth.

3. 'A corn-shock frame comprising a beam, means for supporting the same, supportingarms pivoted at their inner ends in transverse alinement upon said beam, an operating-rod, links longitudinally curved in opposite directions and having their opposite ends pivotally connected to said rod and to said arms at points adjacent to the inner ends of said arms, and a pin arranged upon said beam adj acent to the pivots of said arms and adapted to be engaged by the inner edges of the latter to prevent the pivotal connections between said arms and links from passing the centers of the pivots of the arms when the latter are in their closed position, substantially as shown and described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

EDWARD HENRY DE VILBISS.
